My invention relates to plaster board ceilings and walls supported from overhead floors or nearby wall structures.

A purpose of my invention is to provide a plaster board ceiling or wall of the character indicated that is easy and inexpensive to erect and that well meets the needs of service.

j A further purpose is to lessen the requisite thickness for a Viinal coat of plaster on the room sideof an erected plaster board ceiling or wall of the character indicated by -using ythicker boards and providing supporting structural clip members between the boards that project toward the room only very little beyondA the room face of the boards and that effectively support the board edges so that the boards lie uniformly in one plane.

Building regulations frequently specify that finished ceilingsor walls of the character indicated shall include a total thickness of plaster not less than three quartersof anv inch.

It has been usual practice in the past to make up this4 required three quarter inch total thickness include a three eighth inch plaster board and a surface coat applied wet to the room side of the plaster board of about another three eighth inch.

I use thicker plaster board and athinner coat of applied' plaster, desirably. aking the plaster board live eighths inch thick and the finish coat about one eighth inch, and thereby greatly lessen delay incident tothe time ythat must plaster to dry out, secure a considerably lighter wall in that the plaster board may be made much lighter thanI the same thickness of applied plaster, and by greatly lessening the quantity of the applied plaster make it commercially possible to use a much better grade of plasterv in the applied coat, 'the higher rice for the better grade of plaster belng o set by the smallness of quantity now required for the finishing coat.

A further purpose is to support the boards of a, plaster board ceiling or wall of the character indicated' by furl-,ing strip structural clip members each of which has at spaced oints preferably hook connection to a main`- oor or wall structure and a body along and be allowed for the applied.

between the edges of adjoining boards, stili'- ening the boards from bending, and seating and permanently alining the adjoining edges.

A further purpose is to longitudinally stagger successive boards in furring strip structural clip members with respect to successiveboards in a row of wall boards that are supported by the clips end to end in a plaser board ceiling of thecharacter indicate I place rows of structural clip members between the .rows of end to end wall board,

Like numerals refer to like parts in all figures. Describing in illustration and not in limitation and referring to the drawings The broader features of my invention apply to plaster board `ceilings and walls made up of boards of any area dimensionsv and of any thickness.

Some of the detail featuresfhowever, find particular application for supporting and erecting the standard short length boards now so usual in walls and ceilings.

These standard short boards are sixteen.

inches wide and come in full and half lengths of forty-eight and twenty-four inches respectively, and Figures 1,16and 17 illustrate the furred walls and ceiling of a room made up of a succession of rows of these standard boards, end to end. I

One of the principal features of my invention includes a structural furring strip clip member for seating, supporting and stiifening adjoining boards alongtheir adjoining edges, each furring strip clip member preferably extending along a considerable portion of the length of the supported board. and being itself .supported from the main Hoor or wall structure.

I herein call m structural clip member a furring member 1n that it functions like a furring strip to support wall board or the like at a distance from a main wall structure or main ceiling structure, and further in that like a furring strip one of its important functions is to stiffen the supported board along the length of the board.

Clips of the prior art have not been furring strips inthe sense used herein in that they have notlongitudinally stifened the board supported by them, being` supported upon `alreadytdescribed between the stiifeningmembers usually channels or angles across the inner` faces of the supported boards, and extending transversely to the.

lengths of the board.

I combine a furring strip that has support from the main wall structure with clip members placing the member between the boards and making them of a length to breakjoints when the wall or ceiling comprises rows of short boards end to end.

The form of my furring strip clip member may be considerablymodified according to individual whim and circumstance and I show a few only of these forms at 40, 401, 402, 403, 404, 405, 406 and '40" (Figures 2, 6, 8, 9, 11, 18, 19, 21, 25, 29. and 3o).

The different forms are alike in so far that each seats adjacent edges 41 and 411 of contiguous boards for a. considerable portion of the length of these edges andpresents an inwardly directed flange 42 toward amain Hoor or wall structure which supports the member from movement in direction perpendicular to the supported boards.

The supporting connection between the main floor or wall structure is desirably a able perforations 43 in the flange 42,and preferably longitudinally rigid with respect to the main structure, as in Figures 29 and 30, where the main structure is a wall.

If the maln structure is an overhead floor the supporting connection from the floor to thefurring strip clip members may desirably comprise downwardly directed eye inserts 44 in the floor, andsuspension hooks 45 between the eyes and the perforations .in the furrlng furring'strip clip members, as well as the structural clips that have no supporting connection with the nearby floor or wall, are all preferably one piece members, made by suitably cutting andiforming metal 'sheet material.

The forms of furring strip clip member shown at 40 and 405 tour and are used alike, (Figures 2, 18,19, 29 and 30) so that any advantage of either with respect to the other will normally be in manufacture.

The form40 (Figures 2 and 21.) is cut and stamped from a single thickness of 4heav gauge metalwhile the form 40s isfolded and pressed from lighter gauge metal.

The clip member shown in Figures4 andy 22 is used between the adjacent endslof end to end boards to keep the contiguous edges of the boards even as at 46, Figures 1 and 17.

While the clip 46 is quite satisfactory with sixteen inch width boards, with wider boards I usually prefer to use the furring strip clip board `in that it dgreatly -stifens the' boards across their en s.

` In the XKcorner connection between wall and are 'alike insectional cony wall.

each a stiffening flange 42 for connection tothe main overhead floor structure or main l wall structure.

The corner boards overlap as in Figures ,5,

8, 13 and"12 or do not overlap as in Figures 9, 10 and 28.`

In Figure 5 there is no fastening shown lbetween the corner ceiling boards and the clip member other than themere seating of the edge of the board in the clip. Where the' Wall board is already fastened against move-'- ment inwardly toward the main wall structure there is normally no need for fastening the ceiling board to the wall board other `than .the mere seating of the boards in the clip as indicated in Figure hook presented by the main structure to sult- S 40 and 401 (Figures 2 and 6) are similar ex-l cept that the latter strip is provided with a' strip clip members (Figures 18 and 20). The fl ber is well suited for fastening tov structural edge of the ometimes it is desirable to use the ceiling this event I may use the members 50 presentedvby the mainwall as indicated in Figures 16, 17 and 25. y

rI he form of furring strip shown in Figure 11 1s adapted .to fasten the edge of a ceiling board to the main overhead licor structure or to f asten the top edge of the wall board to the mam wall structure.

A 4Suitable perforations 43 are provided for connecting the flange portion-42 of the strip to the main The clip shown in Figure '10 is used at the where a last board 51 across a ceiling has to connect with a wall board 52 already erected.

Optionaly this clip member may bev replaced by the furring strip member 408 shown in Figures 9 and 28, which fastens to the main wall or ceiling structure or to memT supporting struct-ure, floor or bers such as angles 53 lcarried by the main structure.

The lower flap portions 54 may be left in line with the outside of the wall board and be bent into place after the ceiling board has 54 being bent up a been put in place, and suitable nails or tacks been pushed into its inal position.

The clip shown in Figure 12 may also be used at either end of ceiling board connection with the wall board. Assuming that a room has both walls and ceiling of plaster board furred out fromY main supporting lWalls and a main overhead ioor I may erect ,all the walls first and then the ceiling, may erect two adjacent walls then the ceiling and then the other adjacent walls or. may erect the ceiling first and then the Walls, the operation of erection and the selection of furring strip clip members desirably differing somewhat according to which one of the different sequences is followed, and in each case the boards may have any dimensions. v` e Vhen the Walls are all erected before the ceiling and the ceiling boards lare put up beginning at one corner of the room in successive widths from'wall towall the ceiling and wall boards preferably overlap alongtwo adjacent walls, while along the other adjacent walls the ceilingboards more conveniently end inside the inner wall faces.

Along the first two adjacent walls I may use the structural corner clip member shown in Figure 5, or that shown in Figure 13 or that shownin Figure 12 or may use any one of the corresponding corner furring strip members, and on the other adjacent walls may use the structural clip members shown in.

Figure 1() or one of the corresponding furring strip members, such as that shown in Figure 9 or 'Figure 28, or may use the clip member shown in Fi ure 121, the bottom fiaps Iter the Wall board has 48 being preferably inserted to tie the ceiling and Vwall boards together.

OIf I erect the two adjacent Walls and then the ceiling, beginning the successive widths of ceiling'board at the corner between the adjacent walls, then the ceiling(I and wall boards desirably overlap at all of the walls and I may use the structural clip member of Figure 5 or of Figure 13 or of Figure 12 or the corresponding corner furrin' strip members along all of the walls, workmg from the ceiling ldownward when putting up .the boards of the other Yadj acent walls. t

The last Wall board fastenings are then made at the floor desirably using structural clip members such as that shown at 57 in Figures 7 and 24, either already fastened to place by nails or tacks 58 with the flaps 59 on the room side bent down to pass the bottom edge ofthe board and then after the board .is in place set up to hold it,-or the clip member may be placed loosely over the bottom edge of-thev board While the board is out at the bottom, and then fastened after the bottom of the board has been pushed to placev If I erect the ceiling first I may make the i wall structure without clipping it to the ad` jacent ceiling board.

Advantageous detailfeatures of my invention are directed to a method for erecting the1 1short boards of commerce on` ceilings and Wa s.

In the ceiling shown in Figures 1, 16 and 17 the furring stripclip members 40 are desirably of length a very little less than the standard length of the wall boardsfor example a little less than forty-eight inches where using the forty-eight inch boards.

These clips'are suspended at each end by a hooked hanger 45 that is in turn suspended from the supporting eyes 44 inserted during the construction of the ceiling.

Assuming the main overhead fioor and the main walls^to be concrete and the plaster boards sixteen inches by forty-eight inches, the supporting eyes 44 are preferablyC placed as inserts in the forms for the concrete ceiling, desirably in parallel lines, spaced in the Vrows sixteen inch centers and between the rows forty-eight inch centers (Figure 1). The character of ceiling insert 44 is desirably different 'according to the kind of form used when making the concrete ceiling.

lVhen wooden forms are used the type of eye shown in Figures 18 and 19 is easy tov insert but less convenientwhen the Hoor or wall forms are iron and I prefer to use an insert such as that shown at 441 Fig'ure 20 when iron forms are used for formingithe main structure'. Cbviously the threaded member 60 screwing into the insert 44, Figure 20, may or may not be a rigid portion of the hook members 451 thatl engage the furring strip members 40.

The "perforations 43 in the flanges 42 of the furring strip that receive the hook ends of the members 45, 45', or 452 (Figures 29 and 30) may desirably be elongated vsomewhat vto allow more easy registry with the hook ends when erecting.

Assuming that the wall boards have al-x i ready been placed the method of erecting a ceiling is as follows:

I insert hangers 45 in the ceilin eyes 44,

one in each of the end eyes, that 1s in each of the eyes adjacent either-wall-,and two hangers in each of the intermediate eyes.

`I thenattach the furring strip clip members 40.to the hangers, hooking hook'on han ersl through the holes 43 in the ends of the urring strip clip members.

There arel now parallel lines of the clip members 40 sixteen inches apart and ifi pov the bottom sition to -support the adjacent edges of the end to end boards. i

To insert the boards into the clips I begin for example in the left hand .corner of the room taking rst a one half lengthboard serted into the seat presented by the furring strip ceiling clip 64, the clip being free to swing. AThis leaves the furring strip member 64 extending about one half board length beyond the first board.

I then place one or more clip members 46 on the outer end of the first board.

The clip 65'may or may not have support from the main floor above-as shown it does not have this support, being the clip 46 of Figure 4. y

I now begin with full length boards, siX- teen inches by forty-eight inches putting up one board after another, and the center of the board in every case coming under the row of eyes 44 in the main floor above and at the end to end separations between the successive furring strip clip members.

Each board is pushed into the side` clips 66 while still suiiiciently forward to clear the flange portions of the clips '46 in the middle of the last board end, and then pushed back` to seat in the clip 46 against the last board,

the outer swinging clip yieldingoutwardly sufficient to receive the outer board.v

In following this system of erection the last placed board when sliding 'out the clips edge of the to insert the following board is still sup-- ported on two full sides and half of a third side thereby averting Iany danger of the board tipping during the operation.

When inserting the last board 67 infthe line, which must be cut to `measure I omit the clip 46 (Figure 4) at yits rearward end and in sert several key clips- 68, Figures 3, 14 and'l..

' The last board y67 of each line is cut to a length equal to the distance from the edge of the preceding board to the face of the wall boards. j

The clip member 69 (which is desirably 'that of Figure 10 or Figure 9) is vthen placed on the wall edge of the board 67, Vthe board is' then pushed into position as usual, its wall edge being pushed up enough to allow the clip to be fitted over the edge of thel wallA board. l

The ceiling boards are preferably suitably fastened from upward movement adjacent the walls, as by small nails 70 holding the corner clip. members to the wall boards.

This is to prevent the pushing up of the hoard while applying the plaster.-

-In ,applying this system' to metal. furred walls the vertical Hoor to ceiling one and a half inch angles 50 may be retained, as illustrated in Figures 16and 17', 'or omitted as in Figures 29 and 30.

In the embodiment of Figures l'and 17 'the furring strip members 71 are intended for a conventional showing for any of the suitable furring strip clip members.

The walls vare preferably erected before the ceiling.

I secure the Dclip 57l (Figure 7) to the floor,

insert the lower edge of the board between the flanges, it the' clip 71 to the upper edge ofthe board, then secure the clip to the ver tical angles by suitable wires or wire clips 72. I make the'same use of the clip 46 (Figure 4) as on theceiling and continue the operation similarly as on the ceiling.

The clipmembers at the vertical corners may desirably correspond to the members ,402, 403 oi' 407 shown respectively in Figures 8, 9 and 28, the member preferably extending from the Hoor to a little below the ceiling boards.

The key 68 are inserted` in recesses` 73 cut in the adjacent ends of the boards with which the clips are. to be used.

The keys are provided with non-circular perforations to fit a non-circular shank 74 of a tool 75 yand seated upon the tool are inserted lengthwise of the recesses .73 to the middle of the thickness of the boards.-

'Ihe toolis then given a quarter-turn to the position shown in Figures 14 and 15, the lkey member cutting into the plaster of the adjacent boards as shown.

In view of my invention and disclosure variations `and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the'art, to obain all or part of the benefits of my invention without coping the structure shown, and I, therefore, claim all such in' so far nas they fall within the reasonable spirit and scope ofmy invention. Having thus described my invention, what I claim as new anddesire to secure by .Letters Patent is:
